“…T HE IMPORTANT nonlinear effect of magnetic saturation is a well-known phenomenon, which is carefully considered in the operation of the synchronous machines since early days [1]- [4], [7], [9]- [11], [15]. Where the description of the dynamic behavior has evolved considerably over the years, the representation of saturation did not undergo important changes, except for the introduction of cross-saturation.…”

In this paper, the measurement results of a series of standstill frequency-response (SSFR) tests, performed at different magnetization levels, are discussed. For each data set, an individual -axis model is estimated, which allows seeing the variation of the different parameters as a function of saturation. A global estimator is presented which uses the different data sets to estimate one global model, including the field-to-armature turns ratio. The global estimator is based on an impedance matrix representation of the synchronous machine. This global estimator assumes that only the -axis main inductance is saturation dependent. The individual estimated models justify this assumption. Finally, the relative additional error of the global estimated -axis equivalent circuit with the individual estimated ones is studied.The measurement results discussed in this paper are obtained on a four-pole 130-kVA synchronous machine.
